Gas heating system

The invention discloses a gas heating system which comprises a plurality of gas boilers, a water storage tank, a plurality of first sub-catchment devices, a plurality of second sub-catchment devices, a plurality of make-up pumps, a plurality of pipeline pumps and a plurality of heat exchangers. The water storage tank is connected with the multiple make-up pumps. According to the heating system, the water storage tank, the first sub-catchment devices, the second sub-catchment devices, the make-up pumps and the pipeline pumps are arranged, it is ensured that water supplementation is rapid after heating water is replaced, normal heating is not affected, then the combustion efficiency and the heat exchange efficiency are improved by arranging the gas boilers and the heat exchangers, and therefore the heating efficiency and the heating effect are improved, and the energy consumption is reduced. The overall structure is simple, practical and reliable. 本发明公开了一种燃气供暖系统，包括多个燃气锅炉、蓄水箱、多个第一分集水器、多个第二分集水器、多个补水泵、多个管道泵、多个换热器，
